I will post screenshots later but for now - the issue is that when connecting the Galileo it appears not under "ports" or "other devices" but as an "unknown usb device" in th "universal serial bus controllers"

when trying to update the driver I get that the driver is already updated, when trying to update manually I get that the file is incompatible with 64 bit systems

I've tried installing the inf manually, the cat manually, tried installing the drivers from within the arduino folders but nothing seems to change the fact that it is still an unknown device

I'm not sure I understand the problem. I'd suggest you start a new thread describing the problem (if useful, explain similarity/ies with the one described in this thread) and what you have made so far.
